After upgrading from the NPE-G1 to the NPE-G2 we have had slow input errors. The NPE-G2 gigabit interfaces are located in the back of the router under the fan and power which may be causing the input errors (EMI). Still seeing the input errors after using STP cables. Anyone else experiencing this issue??
Looks like you are running into BUG ID CSCsf32623. The bug should be fixed in 12.4(4)XD4.
Let me know if it helps.
